Since Python dictionary stores key value pairs, it uses hashing operations to store the values. 
It is not necessary for the hash values to be in sorted order. 
So when you print the dictionary the values are displayed on the basis of hash values and so python’s dictionary is un ordered. 
If you want python dictionaries in sorted order, you can use sorted() function.

If want to use ordered dict in python we can use "ordereddict" module in short.
from _ordereddict import ordereddict
kio = ordereddict()
kvio = ordereddict(kvio=True)
# without relax unordered initalisation is not allowed

JSON - Python has a JSON module that will help converting the datastructures to JSON strings. 
Use the import function to import the JSON module.
import json
student = {"101":{"class":'V', "Name":'Rohit',  "Roll_no":7},
           "102":{"class":'V', "Name":'David',  "Roll_no":8},
           "103":{"class":'V', "Name":'Samiya', "Roll_no":12}}
print(json.dumps(student));
Output:
{"103": {"class": "V", "Name": "Samiya", "Roll_no": 12}, 
"102": {"class": "V", "Name": "David", "Roll_no": 8},

If you are using python 2, then you can add a comma after the print function like this:

for i in range(10):
    print i, # <- notice the comma at the end
will output:

0 1 2 3 4 5 6 7 8 9
In python 3, print is now a function and will take an argument, called end like this:

print(i, end = " ")

Method      Description
clear() ===>Removes all the elements from the dictionary e
copy() ====>Returns a copy of the dictionary

Data structures(list,tuple,strings,dictionary,sets)
===========================================================
Diff between tuple and sets
tuple:Immutable type,can contain dubplicates also defined in() whereas indexed
Sets:Mutable type,cannot contain dubplicates and defined in {}
   empty set has to define like

Multiprocessing Vs Multithreading :
  Multiprocessing is when the part of program can be executed by separated processes.
  
The cost of multiprocessing is really high.

MultiThreading:
  The main program is divided into sub threads.
  Here to decide the number of thread is a big challenge , taking more number of threads can deduce ur latency since
  thread concurrency has limit , after a limit it slows down the process.
